SPECIFICATION forming part of Letters Patent No. 769,001, dated August30, 1904.

4 Application filed February 19, 1904. Serial No. 194,355. (No model.)

To all whont it may concern:

Be it known that I, HARRY GORDEN LAW- RENoE, a citizen ofthe UnitedStates, and a resident of Salt Lake City, in the county of Salt Lake andState of Utah, have invented a new and Improved Sink-Strainer, of whichthe r following is a full, clear, and exact descrip.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 represents in sectional view a sink with a preferred form of myinvention attached thereto. Fig. 2 is a perspective View of an ordinarystrainer commonly applied tosinks provided with means for attaching myimproved device thereto. tive View of my improvedstrainer, and Fig. 4 isa fragmentary sectional view showing a method of attaching it to theordinary strainer.

In the drawings, 1 represents a sink with bolts or studs 2 connecting toitasupportingframe 3, which carries the waste-pipe A. .On the bottom ofthe sink is a ledge 5, designed to support an ordinary strainer 6, asshown. This strainer is provided with a depressed portion 7, which isprovided with perforations, as shown.

My strainer consists of a perforated or foraminous metallic receptacle8, which is attached to the strainer 6 by means of lugs 9, with whichthe latter is provided, and which extend through holes 10 in the upperpart of the strainer 8. The strainer 8 is preferably shaped as shown,with a vertical cylindrical portion, a bottom, and a flared portion atthe top fitting the upper strainer 6, as shown.

Fig. 3 is a perspec- All these parts are provided with perforationswhich are preferably considerably smaller than the perforations in thestrainer 6. Within the strainer 81 preferably place a cleaner 11,attached to a rod 12, hung by means of a ring 13 from the center of thestrainer 6.

It will be obvious that this'device will stop many things which mightpassthrough the ordinary form of strainer that is employed in sinks.forexample, cofiee-grounds and the like. It will also stop a largepercentage of the grease that passes through the strainer 6. Beingformed, preferably, of one piece of metal, it can be manufactured atvery small expense, and it can be applied to any sink without expensivealterations. It fits down within the house side of the trap,isself-supporting when once put in place, and does not require theservice of a skilled mechanic to place and replace it for cleaningpurposes. It may be readily lifted out by means of the rod 12 and ring13 in an obvious manner.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination of 'a sink having a depression. aperforated plate seated in said depression, outwardly-projecting lugs onsaid plate, and a perforated receptacle attached to said lugs.

2. In a sink-strainer, the combination of a perforated plate, aperforated receptacle, means for attaching said receptacle to the plate,

a rod depending from said plate into said rece'ptacle, and a plate onthe bottom of said roc.

'3. A sink-strainer comprising a perforated plate, a perforatedcylindrical receptacle having a perforated bottom and a perforatedconicaltop portion extending from said cylindrical receptacle and a rodextending from said plate into'said receptacle and having a platethereon.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
